I'm going to go out on a limb here and agree with Zelot. I know it's surprising, but when you start just playing the game for its own sake instead of trying to be better than the next guy, it's a lot more fun and a lot less frustrating.
On another note, it really goes both ways. Metagaming wouldn't happen if people wouldn't make a big deal and just RP around it anyway. If I had a credit for everytime I flew into a system and someone said " Phantom! I know you!" before I ever said anything, Battleships would pay for themselves, but instead of going "RAWR, Y U MAKE METAGAME AT ME!?" I stick to my RP and just roll with it. Amazing how that works, huh?
